Hi,
I'm planning to make an amplifier for a pair of 4ohm, 40w nominal fullrange speakers (mostly for PC use).........
.......can anyone please suggest me a good one??
I don't want it to be to costly or a hard to find one (most importantly I'm a novice,so I don't want it to be a very complex one either)
PCB designs or images are very much welcome.

If you're using them with a PC, pure digital is the way to go. However, pretty much all the digital chipsets are SMD, which is not recommended for a beginner. (There might be kits with the SMD components already soldered onto the board, but I'm not aware of any.)
